Product Name: 71mm High Speed Steel Screw Barrel for Granules Machine Material: Stainless Steel Feature: Wear Resistant Technics: Casting Application: for Extruder Trademark: HS Transport Package: Wooden Cases Specification: as require Origin: Jiangsu Product Description (price for 71MM Screw elements: 1.3 USD per mm)(price for TSE-75 barrel: 650 per piece 290mm)SPECIFICATONS1. Extruder replace parts2. High quality, high accuracy3. Screw: W6Mo5Cr4V2.38CrMoAl. SKD11. SACM645 etcDescription:The flexible modular principle is realized with screw barrel sections from the wideRange ofdifferent designs possible. Fast, intensive and uniform heating ofthe screwBarrel section is ensured by electrical heaters. The barrel sections are cooled withWater, by means ofan internal bore system, with bores arranged close to the insideBarrel wall.Barrel sections are available as:Closed barrel sectionBarrel section with opening for material feed or for devolatilizationThe processing section is provided with stainless steel plates as aprotection againstAccidental contact.Screw Elements: High-speed steel W6Mo5Cr4V2, nitrogen treatment.Screw Shaft: High performance alloy steels, 40CrNiMoA; With standing high load, EtcDescriptionThe inter meshing screws co-rotate and wipe each other with narrow clearance so thatNo residues are left in the screw flight and clean effort is thus reduce.Screw elements with various pitches and lengthsKneading blocks with various angles ofstagger, numbers ofkneading disks and diskWidths.Screw tips to fix the screw set axiallyGear teeth connection to ensure power flow between the screw shaft and screwElements.Features:1. Screw components designed by computer aids is kneading type, has excellent self-cleaning function, the new kneading block design effectively avoid the problems of overheating and energy consumption.2. According to process system and formula requirements, the unit can optimize its L/D ratio, barrel structure, screw array, venting number and location, feeding method, electrical control methods etc. For rational allocation.Packaging for exports:Package: Wooden case or Using Anti-rust oil processing, then use stretch film cover extruder against moisture damage.Shipping: By sea or By expressCompany InformationNanjing HaiSi Extrusion Equipment Co., Ltd is aHigh-Tech company, which is composed of well-experienced team in R&D, manufacturing technique, sales service and basing on extruder industry for many years.
